NC control Validation and Simulation Process

1. Overview

The NC (Numerical Control) validation process integrates real-time machine control with digital simulation to ensure that machining operations are safe, efficient, and optimized—directly from the NC program. By replicating actual machine behavior, this workflow verifies toolpaths, material removal, and collision avoidance before physical production begins.

2. Prerequisites

Before starting the validation process, ensure the following prerequisites are met:

• A complete project file including part, toolpaths, machine files, and fixture setup.

• The NC Code file generated from the process is available.

• NC control installation for the current version of GO2cam.

3. Process Workflow

Step 1: Load the project and machine setup

• Open the project file with the part, machine, and fixture setup.

• Confirm all geometry, tooling, and setup parameters are configured.

• This prepares the simulation environment with accurate physical context.

Step 2: Load the NC Code File

• Load the NC code file into the system.

• This initializes the machine controller (e.g., FANUC), ensuring:

  • Accurate motion logic

  • Proper axis limits

  • Controller syntax fidelity

Step 3: Launch NC Control Module

• Open the NC Control module.

• Replace standard MTE simulation controls with a real-time NC controller interface.

• The system executes G-code exactly as the physical machine does, enabling authentic code-level validation.

Step 4: NC Code Editing and Validation

• Use the NC Code Editor (Camparser) to:

  • View and directly edit G-code

  • Apply changes and instantly observe effects in the 3D simulation

• This live connection between editor and simulation enables true NC code validation without external reruns or exports.

Step 5: Core Simulation Functions

The NC Control module performs comprehensive validation through five key stages:

Step 6: Editing and Recomputing NC Code

If adjustments are needed (e.g., adding a spindle movement):

• Unlock the Camparser editor.

• Insert or modify G-code/M-code commands.

• Lock the Camparser.

• Click Execute (green button) to apply updates.

• Instantly verify the changes in the 3D simulation.

4. Final Approval and Release

Once the simulation confirms no collisions, correct final geometry, and optimized toolpaths, the NC program is validated and ready for safe transfer to the CNC machine for production.
